No DBX but, on the other hand CLA has the LA-3A and 2 1176 models - Blacky and Bluey.
John, I just posted a thread updating (well, totally discrediting is more like it) my previous statement about IK vs NI vs Waves.
Long story short - Waves pack in a lot more punch, probably even more than the original unit, and the possibilities in terms of shaping your sounds are, imho, totally worth it. It's a 1176 on steroids.
But both IK and NI come very close to the original as far as I can tell/assume.
